保留属性顺序的java xml库

我正在编写一个Java程序，该程序读取xml文件，进行一些修改并写回xml.

I am writing a java program that reads a xml file, makes some modifications, and writes back the xml.

使用标准的Java xml DOM api，不会保留属性的顺序.也就是说，如果我有一个输入文件，例如:

Using the standard java xml DOM api, the order of the attributes is not preserved. that is, if I have an input file such as:

<person first_name="john" last_name="lederrey"/>

我可能会得到一个输出文件:

I might get an output file as:

<person last_name="lederrey" first_name="john"/>

是正确的，因为XML规范指出order属性并不重要.

That's correct, because the XML specification says that order attribute is not significant.

但是，我的程序需要保留属性的顺序，这样人们就可以使用差异工具轻松比较输入和输出文档.

However, my program needs to preserve the order of the attributes, so that a person can easily compare the input and output document with a diff tool.

一种解决方案是使用SAX(而不是DOM)处理文档: DOM处理后XML属性的顺序

One solution for that is to process the document with SAX (instead of DOM): Order of XML attributes after DOM processing

但是，这不适用于我的情况，因为我需要在一个节点中进行的转换可能取决于整个文档的XPATH表达式.因此，最简单的方法是拥有一个与标准Java DOM库非常相似的xml库，不同之处在于它保留了属性的顺序.

however, this does not work for my case, because the transformation I need to do in one node might depend on a XPATH expression on the whole document. so, the simplest thing would be to have a xml library very similar to the standard java DOM lib, with the exception that it preservers attribute order.

有没有这样的图书馆?

ps:请避免讨论我是否应该保留属性顺序.这是一个非常有趣的讨论，但这不是这个问题的重点.

ps: please, avoid discussing whether I should preserve attribute order or not. this is a very interesting discussion, but it is not the point of this question.
